Two degree of freedom motion control of an energy optimized aircraft ram air inlet actuators

Kurzfassung

A high accurate position control structure for energy optimal actuation of an aircraft ram air inlet actuator is presented in this paper. The structure comprises a feedforward planning of the energy optimal reference motion profile, and a feedback position control with an inner loop for speed tracking control using a robust two degree of freedom (inverse disturbance observer) controller. The motion control structure is validated by simulation and experimental results under different load conditions.
